Why do I have a white on black background?
After replacing the touch screen on a second generation iTouch I have a white on black background, from what I read this should not even be an option on a second generation iTouch. Plus it is very hard to see and the display is predominately white. How can I fix this?
Hold the top and bottom buttons at the same time until an Apple logo appears. This will perform a soft reset. If that doesn't work, there is probably something wrong with the connection to the screen. I'd recommend taking it out, blowing a little compressed air over the connections, then re-installing it.
Hope this helps.
